The data tables and the RSNetWorx for DeviceNet screens and windows used to configure the data tables are also described. The following table identifies what this chapter contains and where to find specific information.

20 1-4 Before You Begin The 1771-SDN scanner module can also be used to bridge a DeviceNet network with another network. Configuring Devices and Data Collection on Higher-Level Networks Via PLC-5/SDN Industrial workstation running RSView Laptop PC running RSNetWorx ControlNet, DH+, or Ethernet Network Configuration of device using RSNetWorx (Chapters 4 & 5) SDN scanner module DeviceNet Network Collection of status or alarm data (Chapter 6) Target Device to be configured Source Device to collect data Address Density and Discrete I/O You can use three addressing methods with your 1771-SDN scanner module. The number of discrete I/O bits you have available for data transfer is affected by the addressing mode selected. Addressing Mode Discrete Inputs Discrete Outputs 2-slot 0 bits 0 bits 1-slot 8 bits 8 bits 1/2-slot 24 bits 24 bits

21 Before You Begin 1-5 The concept described below applies to both input and output data tables. For example, when using your 1771-SDN in 1-slot addressing mode, you have eight bits of discrete input and eight bits of output available. = bits reserved for 1771-SDN and processor communication = bits available for discrete data transfer In the scanner s input and output data tables, there is one byte of memory that is reserved for communication between the processor and the scanner. Processor-specific responses from the scanner are read by the processor in this byte of the input data table. Scanner-specific instructions are written to this byte of the output data table. 0 bits for discrete data transfer 2-slot addressing In 2-slot addressing mode, the only memory that would have been available for discrete data transfer (8 bits) is taken up by scanner/processor communication. 8 bits for discrete data transfer 1-slot addressing In 1-slot addressing mode, there are 16 bits: eight bits for scanner/processor communication, and eight bits for discrete data transfer. 24 bits for discrete data transfer 1/2-slot addressing In 1/2-slot addressing mode, there are 32 bits: eight bits used for scanner/processor communication, and 24 bits for discrete data transfer. More The address density is set via dip switches on the 1771-SDN module and 1771 chassis. For more information about setting your module s address density with switches, refer to the 1771-SDN Scanner Module Installation Instructions, publication For more information about 1771-module addressing, refer to chapter 3 and to your PLC programmable controller system-level installation manual and design manual. Allen-Bradley Replacements

22 1-6 Before You Begin Communicating with Your Devices A strobe message is a multicast transfer of data (which is 64 bits in length) sent by the 1771-SDN module that solicits a response from each strobed slave device. There is one bit for each of the possible 64 node addresses. The devices respond with their data, which can be as much as 8 bytes. A poll message is a point-to-point transfer of data (0-255 bytes) sent by the 1771-SDN module that solicits a response from a single device. The device responds with its input data (0-255 bytes). A change of state message is a transfer of data sent whenever a data change occurs. A user-configurable heartbeat rate can also be set to allow devices to indicate proper operation during intervals between data changes. This does not solicit response data, but may receive an acknowledge message. A cyclic message is sent only at a user-configurable rate, such as every 10 ms. The 1771-SDN module communicates with a device via strobe, poll, change of state, and/or cyclic messages. It uses these messages to solicit data from or deliver data to each device. Data received from the devices, or input data, is organized by the 1771-SDN module and made available to the processor. Data received from your PLC-5 processor, or output data, is organized in the 1771-SDN module and sent on to your devices. IMPORTANT Data from a single device can be mapped to separate 1771-SDN module memory locations. For example, On/Off values can be mapped to one location, diagnostic values to another, etc. This is known as map segmenting. This concept is illustrated by byte A, stored separately, as segments A1 and A2. Throughout this document, input and output are defined from the PLC-5 processor s point of view. Output is data sent from the PLC-5 processor to a device. Input is data collected by the PLC-5 processor from a device. All data sent and received on a DeviceNet network is in byte lengths. A device may, for example, produce only two bits of input information. Nevertheless, since the minimum data size on a DeviceNet network is one byte, two bits of information are included in the byte of data produced by the device. In this example (only two bits of input information), the upper six bits are insignificant SDN Scanner Module Input Data Storage A1 B C A2 D E E Byte input from the devices to the PLC-5 processor DeviceNet Devices A1 Input Data From DeviceNet Devices A2 B D E C Output Data Storage X Y Y Y Y Z output from the PLC-5 processor Output Data To DeviceNet Devices Y X Y Y Z

23 Before You Begin 1-7 Communicating with Your PLC-5 Processor A block transfer read (BTR) is a block transfer of data from the 1771-SDN module to the PLC processor. The processor is reading the data collected by the 1771-SDN module (i.e., DeviceNet input data). A block transfer write (BTW) is a block transfer of data from the PLC processor to the 1771-SDN module. The processor is writing the data to the 1771-SDN s memory (i.e., DeviceNet output data). Your processor communicates with the 1771-SDN scanner module via block transfer reads, block transfer writes, and DIO transfers. Input data, gathered from the network s devices, is organized within the 1771-SDN and made available for the processor to read. The 1771-SDN module does not send data to your processor. Data transferred between the module and the processor must be initiated by the processor. Output data is sent, or written, to the scanner by your processor. This data is organized in the 1771-SDN module, which in turn passes the data on to your scanned devices via strobe, poll, change of state, or cyclic messages.

24 1-8 Before You Begin What 1771-SDN Module Data Tables Are and What They Do To manage the flow of data between your processor and the network devices, the 1771-SDN module uses the following data tables SDN Module Configuration Table Scanlist Table Device Input Data Table Device Output Data Table Device Idle Table Device Failure Table You can configure two of these data tables through RSNetWorx software. These two tables are stored in the 1771-SDN module s non-volatile memory and used to construct all other data tables: Scanner Configuration Table (SCT) Scanlist Table (SLT) The Scanner Configuration Table (SCT) The SCT controls basic information your 1771-SDN module needs to function on your DeviceNet network. It tells your 1771-SDN module: if it can transmit and receive input and output data how long it waits after each scan before it scans the devices again when to send out its poll messages The Scanlist Table (SLT) The SLT supports I/O updating for each of your devices on the network. It also makes it possible for your 1771-SDN module to make device data available to your processor. The SLT tells your 1771-SDN module: which device node addresses to scan how to scan each device (strobe, poll, change of state, cyclic or any valid combination) how often to scan your devices

25 Before You Begin 1-9 exactly where in each device s total data to find the desired data the size of the input data/output data exactly where to map the input or output data for your processor to read or write Interscan delay is the time between I/O scans (polled and strobed). It is the time the 1771-SDN module will wait between the last poll message request and the start of the next scan cycle. Background poll ratio sets the frequency of poll messages to a device in relation to the number of I/O scans. For example, if the ratio is set at 10, that device will be polled once every 10 scans. User Data In This Table Configured Tables SCT basic operation module parameters interscan delay background poll ratio SLT device-specific identification data data transfer method transmit/receive data size input and output data source and destination locations RSNetWorx Configuration Screen 1771-SDN Module Configuration Scanlist Editor (SLE) Edit Device I/O Parameters These values can be configured automatically through the AutoMap function or manually through the Data Table Map. RSNetWorx Software as a Configuration Tool RSNetWorx for DeviceNet software is used to configure the 1771-SDN module s data tables. This software tool connects to the 1771-SDN module over the DeviceNet network via a PC RS 232 interface (1770 KFD module), or PC Card (1784-PCD, -PCID, or PCIDS). TIP RSNetWorx for DeviceNet software can also communicate with the 1771-SDN module via a ControlNet, Ethernet, or Data Highway Plus network. See chapter 5. Allen-Bradley Replacements

26 1-10 Before You Begin The configuration screen map below shows the RSNetWorx for DeviceNet screens used to configure the 1771-SDN module and the navigation paths between them.

29 Chapter 2 Planning Your Configuration and Data Mapping Your Devices This chapter introduces questions you should ask before configuring your 1771-SDN Scanner. In addition, it presents an example DeviceNet network and I/O data mapping scheme for a photoeye and a RediSTATION operator interface module. The following table identifies what this chapter covers and where to find specific information. For information about See page What You Need to Know 2-1 Beginning the Process 2-1 The Example Network 2-2 Example Network Devices 2-2 Photoeye Input Data Mapping 2-7 Mapping Photoeye Input Data for a Block Transfer Read 2-8 RediSTATION Operator Interface Data Mapping 2-4 Mapping RediSTATION Input Data for a Block Transfer Read 2-5 Mapping RediSTATION Output Data for a Block Transfer Write 2-6 What You Need to Know To map data via your 1771-SDN Scanner module, you must understand: your network requirements how input data is mapped how output data is mapped Beginning the Process Planning before configuring your 1771-SDN module helps make sure that you can: use your memory and bandwidth efficiently cater to device-specific needs and requirements give priority to critical I/O transfers leave room for expansion Allen-Bradley Replacements 1

30 2-2 Planning Your Configuration and Data Mapping Your Devices A very important question to answer is what is on your network? You should be familiar with each device s: communication requirements I/O importance and size frequency of message delivery You should also ask how might this network appear in the future? At this point in your planning, it is advantageous for you to have some idea of how the network could be expanded. I/O data mapping can be performed automatically by the RSNetWorx software. But when mapping your I/O, you also have the opportunity to allot room for future I/O. This can save time and effort in the future. For example, RSNetWorx will automatically map the devices as efficiently as possible, but the result is that multiple devices may share the same word location in memory. However, you can also have the system map the devices such that no two devices share the same memory location by selecting the Dword align option when performing automapping. You can manually map the devices if you need to assign them to specific memory locations. For details refer to the Help screens provided by the RSNetWorx for DeviceNet software. Additional support can be found at the Rockwell Software website: The Example Network The following example illustrates a data mapping plan for a DeviceNet network. Note that even if the mapping is performed automatically by the RSNetWorx software, you must know where the devices are mapped in order to use them in your network. Example Network Devices This example network has the following devices: a PC running RSNetWorx for DeviceNet software a 1771-SDN Scanner module interfacing a PLC-5 processor with DeviceNet a Series 9000 photoelectric sensor (strobed) a RediSTATION operator interface (polled)

31 Planning Your Configuration and Data Mapping Your Devices 2-3 IMPORTANT In the following example, output is data sent to a device from a controller. Input is data collected from a device by a controller.
